MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Oct. 1'7, 1911.

Application filed January 4, 1911. Serial No. 600,745.

T 0 all whom it may concern:

Be it known that I, TOMMY J. CONVERSE, a citizen of the United States,residing at Bellingham, in the county of Whatcom and State ofWashington, have invented a new and useful Music-Leaf Turner, of whichthe following is a specification.

This invention relates to music leaf turners, one of its objects beingthe provision of simple means whereby air, under pressure, can beutilized for turning the sheets successively either to the right or tothe left, the mechanism employed being simple durable and compact inconstruction and accurate in operation.

A further object is to provide a novel form of sheet or leaf engagingdevice which insures the proper turning of the sheet or leaf withoutdanger of tearing or otherwise mutilating it and without obscuring anyof the printed matter upon the sheet.

Another object is to provide a leaf engaging member which can be readilymoved into or out of operative position.

WVith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings: Figure 1 is a rear elevation of the music leaf turner,the air forcing means being removed and one of the cylinders and thebuffer adjacent thereto being shown partly in section. Fig. 2 is a planview of the parts shown in Fig. 1. Fig. 3 is an enlarged section throughthe heads of the leaf engaging devices and showing one of the turningarms and its sheave. Fig. 4: is a section on line AB Fig. 1, said figurebeing on an enlarged scale. Fig. 5 is a sec tion on line O-D Fig. 1,said figure being on an enlarged scale. Fig. 6 is a rear elevation ofthe air forcing means used in connection with the mechanism shown inFig. 1. Fig. 7 is a section on line EF Fig. 6, the pedal and its stembeing shown in elevation. Fig. 8 is a perspective view of one of theheads and of portions of the hangers connected thereto.

Referring to the figures by characters of reference 1 designates a framehaving a cross strip 2 adjacent the top thereof and which is connectedto the top of the frame by connecting strips 3. Secured to theseconnecting strips and adjacent the sides of the frame are cylinders 4;the outer ends of which are open and have buffers or cushions 5projecting thereinto, said bufiers being attached to the sides of theframe. The inner ends of the cylinders are provided with inlet pipes 6connected, as by means of flexible tubes 7 to cylinders 8 supported byan inclined foot board 9 which is shown in Figs. 6 and 7. Each of thesecylinders 8 has a piston 10 from which extends a stem 11. A head 12 isarranged at the upper end of the stem and constitutes a pedal. Springs13 are located within the cylinders 8 and serve to support the pistons10. -It will be apparent, therefore, that when one of the pedals 12 isdepressed, air will be forced from the cylinder thereunder into one ofthe cylinders 41 and, when the other pedal is depressed, air will beforced from its cylinder to the other cylinder 4.

Longitudinally extending strips 1 1 are secured to the bottom of frame 1and to the cross strip 2 and are connected, adjacent their ends, bycross strips 15. A clamping member 16 is arranged parallel with thestrips 14 and is attached to the middle portions of the cross strips 15,this clamping member being fixed relative to the cross strips and beingbowed transversely, as indicated particularly in Figs. 4: and 5. A rod17 is mounted for rotation within brackets 18 secured to the crossstrips 15 and has a clamping strip 19 fixedly attached to it and whichis of the same transverse contour as the clamping member 16, the twostrips 16 and 19 being held normally in contact by means of springs 20which embrace the said strips as shown. The two clamping strips 16 and19 are bowed in opposite directions so that the outer or free edgeportions diverge, thus forming curved or rolled backings for the leavesor sheets when they are turned to the right or to the left by means ofthe mechanism hereinafter described. A handle 21 extends from rod 17 andby means thereof the rod can be readily rotated so as to cause themovable clamping member 19 to swing away from the strip 16. Springs 20,as heretofore stated, operate to bind the two clamping members 16 and 19together under normal conditions.

Ears 22 extend forward from the middle portions of the cross strip 2 andthe top of frame 1 and have a pivot pin 23 mounted within them. Upperand lower sheaves 24 and 25 respectively are loosely mounted upon thispivot pin and are spaced apart by means of washers 26 or the like. Theupper face of the lower sheave has an arcuate shifting arm 27 pivotallyconnected to it and having a terminal runner 28, there being an engagingtooth 29 back of the heel of the runner but, with said runner,projecting beyond the convex edge of the arm. The pivoted end of the armis enlarged, as indicated at 30, and is constantly contacted by a spring31 secured at one end to the sheave and serving to press the runner 28outwardly toward the periphery of the sheave. The upper sheave 24 issimilar in all respects to the sheave 25, the arm 27 thereon, however,being pivotally mounted upon the lower face of the sheave and beingextended in a direction opposite to that in which the other arm 27 isextended. Longi tudinally channeled heads 32 are connected to the pivotpin 23 by means of ears 33, these heads being designed to swing in arcsabout the sheaves 24 and 25 and the ears 33 of the various heads beingnormally nested, as shown particularly in Fig. 1, so that the variousheads may lie close together when ex tended either to the right or tothe left of the pivot pin. Each head has a lip 34 extending therefromand between its ears 33, said lip projecting between the sheaves 24 and25 and being contacted by the runner 28 of the adjacent arm 27. All ofthe lips have their free ends disposed on a line concentric with the pin23 and when the sheaves are set in motion, the runners 28 are adapted totravel along the free ends of the lips in the manner hereinafter setforth and as will be apparent by referring to Fig. 3. Lugs 35 extendupwardly from the heads 32 and a spring 36, which is attached to the capof the frame 1, bears against the outermost lug so as to hold it, andits head 32, pressed back toward the frame, whether the heads areextended to the right or to the left of the pivot pin. This arrangementof parts has been illustrated in Fig. 2. Each head 32 has two separatehangers 37 pivotally mounted in the upper portion thereof and eachhanger is provided at its lower end with a wing 38 of celluloid or othertransparent material. It will be apparent that either of the hangers canbe swung upwardly within the head so as to bring the wings above theupper edge of the sheet to be engaged, and can subsequently be permittedto swing downwardly so as to contact with opposite faces of the sheet.By connecting the hangers to the upper portions of the heads 32, thesehangers, when swung downwardly between the sides of the heads, will bedrawn together so as to positively. clamp upon the leaf or leavestherebetween. Each of the sheaves 24 and 25 has a cord, preferably ofmetal, wrapped therearound as indicated at 39, one end of the cord beingattached to the rod 40 of a piston 41 located in one of the cylinders 4while the other end of the cord is connected to a spring 42 which, ifdesired, can be in the form of a rubber band, this spring pulling uponthe cord so as to hold it taut under all conditions.

In using the apparatus, the sheets to be turned are placed in propersuccession between the wings 38 connected to the respective heads sothat each sheet will be located between the two wings of one head. Thesewings are brought into position between the sheets by swinging themdownwardly in the manner hereinbefore described. After the varioussheets have been properly placed, the wings and heads are all turned tothe left of the apparatus where they are held by the spring 36 pressingagainst the outermost lug 35. Under normal conditions the sheaves 24 and25 are so positioned that the arms 27 are arranged with their pivots directly back of the pin 23. It is of course to be understood that theleaves to be turned are held at their inner or back edges in the clampmade up of the strips 16 and 19. To turn the first sheet to the right,the proper pedal 12 is depressed and air is forced by its piston 10through the pipe connection to one of the cylinders 4 and thus actuatesthe piston 41 so as to cause it to pull on cord 39 and rotate the sheaveto which the cord is connected. Runner 28 on the arm 27 carried by thissheave slides along the lips 34 and, as it leaves the outermost lip 01',in other words, the lip of the front head 32, spring 31 will swing therunner outwardly and thus bring the tooth 29 into engagement with saidoutermost lip. Obviously, therefore, further rotation of the sheave willresult in the movement of said outermost head therewith and,consequently, the turning of the sheet connected to it. The piston 41comes into contact with the buffer 5 as soon as the sheave has made aone half revolution. When the pedal 12 is released, spring 13 returns toits normal position and air is thus withdrawn from the cylinder 4 andthe piston permitted to return to its normal position under the actionof the spring 42. The sheave 25 will therefore be rotated in theopposite direction and the tooth 29 will withdraw from engagement withthe lip and the shifted head 32 will be retained by the end portion ofthe spring 36. Arm 27 will thus be brought back to its initial positionand when the said pedal is again depressed, the foregoing operation willbe repeated. To swing the leaf back to the left of the apparatus, theother pedal 12 is depressed thus setting in motion the other sheave andthe arm carried thereby, said arm cooperating with the outermost head atthe right of the apparatus to move it back to its initial position atthe left.

Vhat is claimed is 1. A music leaf turner including channeled headsmounted for rotation about a common axis, hangers pivotally mountedwithin the upper portions of the heads, said hangers being disposed inpairs, the walls of the channels constituting means for binding thehangers together when suspended from the heads, and means under thecontrol of the operator for successively moving the heads about saidaxis.

2. A music leaf turner including longitudinally channeled heads mountedfor rotation about a common axis, a pair of hangers pivotally mountedwithin the upper portion of each head, said hangers being normally heldtogether by the walls of the channels in the heads, means under thecontrol of the operator and movable in one direction about said axis toengage and shift one of the heads, and elastic means placed under stressduring such movement and constituting means for returning said headmoving means to its initial position.

3. A music leaf turner including channeled heads mounted for rotationabout a common axis, a pair of hangers pivotally mounted within eachhead, the hangers of each pair being normally clamped together by thewalls of the channel in which the hangers are mounted, leaf engagingwings extending laterally from the hangers, said wings beingtransparent, upstanding projections upon the heads, yielding means forengaging the projections to hold the heads in either of two positions,means mounted for rotation about said axis for engaging and shifting theheads one at a time during successive movements of said means in onedirection, mechanism under the control of the operator for shifting saidmeans in said direction, and an elastic element for automaticallyreturning said means to its initial position subsequent to each of saidmovements.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
